Might as well throw my two cents in here. Mine have worked amazingly so far. One problem I've had is last weekend the back pane along with the foam was starting to seperate, now this is during the middle of winter and still not leaving my mask in my truck. So not sure if this is just problem with mine or with the whole bunch of lenses.
I will say i'm a bit disappointed in the selection of colors for the profiler. May still be going back to i4's and keeping this as a backup. oh and yea, the coating does stay on this time, my old blue lense for my grillz was flaking after a week when I had them a few years ago.
